Features & Product Details

If you are running more modifications that require more boost, then it is a good idea to run a colder plug. The NGK Iridium IX Spark Plugs are designed to offer extreme ignitability, improved throttle response, and superior anti fouling.

The fine iridium tip is more durable, and longer lasting than your conventional spark plug. Iridium alloy has an extremely high melting point, which is needed for the high performance boxer engine. Other features for the NGK iridium plugs are Trivalent Metal Plating, superior anti-corrosion, and anti-seizing properties.

These are recommended for higher horsepower applications where a higher heat range number or colder plug will increase the spark plug’s ability to dissipate heat.

Ej207 bliss 5 years agob-dub
I have a late version 8 EJ207 and these are the recommended heat range from the factory in these JDM motors. I am happy to know that I can buy them here with no hassle. I couldn't find any locally (what gives?). Moreover, they are a good price on here so I don't see the need to leave my house in search of them. I order two sets at a time to spread out the shipping costs, and I'll have them at the ready should I need them at a moments notice. \common sense.
